Xcode script for generating/synthesizing properties

Question

Does anybody have an Xcode script for generating @property and @synthsize directives for instance variables in a class?

Answer 1

Here's one I wrote up yesterday to do the @property directives before coming across this question a few hours later. It's a simple text filter and would be trivial to extend it to @synthesize directives (add an appropriate when clause to the case statement and make appropriate additions to the when block_end condition), and not much more work to extend it to handle multiple occurrences of @interface/@implementation in one file (by tracking their names --- it can be done through regexp captures, as everything else is in the script):

#! /usr/bin/ruby

# -------------- Basic Definitions -----------------------------

doc = "%%%{PBXFilePath}%%%"

# regular expressions

search_exp = /[[:space:]]*([[a-zA-Z0-9]]*)[[:space:]]\*([a-zA-Z0-9]*)/
interface_start = /@interface/
block_end = /^\}/

#initializing variables

properties_list = []
properties_string = ""
reading_interface = 0

#---------------- Start Processing -----------------------------

file = File.open(doc, "r").readlines

file.each do |line| 

# capture the regular expression matches only in the 
# interface declaration and print out the matching
# property declarations

  case line

  # start capturing
  when interface_start
    reading_interface = 1
    puts line

  # capture and keep in properties_list
  when search_exp
    if (reading_interface == 1) then
      data = Regexp.last_match
      properties_list <<  data
    end
    puts line

  # unpack properties_list and print out the property
  # declarations
  when block_end
    if (reading_interface == 1) then
      reading_interface = 0
      properties_list.each do |pair|
        properties_string << "@property (readwrite, copy) #{pair[0].lstrip};\n"
      end
      puts line
      puts "\n" + properties_string
    end
  else puts line
  end

end

I run this using "no input" and "replace document contents" as the options for I/O in the User Scripts editor.
